There is a 24hour supermarket 100yards from Eden, where you can go with a pass out, sit back and chill out with a €2 liter bottle of water!
There are always ways to get around a problem!
Don't do it too often or Security will get suspicious.
Thanks for the tip - bit worried if I get clocked going off to the supermarket I might not get back in the club where all my mates will be! I don't mind paying 4-5 euro's for a bottle of water outside but a tenner?!!!
